Calculate the pH of a solution prepared by dissolving .37 mol of formic acid and .23 mol of sodium formate in water sufficient to yield 1.00 L of solution. The Ka of Formica acid is 1.77x10^-4.
And please show how to do it.

A) 2.1
B) 10.46
C)3.55
D)2.31
E)3.95

answer; ///(u-235); ///is the correct

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance
